Description

The invention relates to textile treatment agents containing bisulfite-blocked polyisocyanate Prepolymers and special plasticizer formulations contain a process for the production of these textile treatment agents and their use.

The modification of the handle of textile materials is of great importance. Also the non-shrinking equipment to prevent shrinking, shrinking and entering textiles under the influence of moisture is an important one Part of the textile finishing. DE-PS 24 14 470 describes for example the finishing of textile materials with bisulfite-blocked polyisocyanate prepoly meren. These bisulfite-blocked polyisocyanate prepolymers are produced by reacting polyisocyanates with polyhydroxy compounds and a then blocking the isocyanate end groups with bisulfite. Since it is the bisulfite-blocked polyisocyanate prepolymers around self-crosslinking compound no catalysts need to be added in the equipment step become. However, it is disadvantageous that the bisulfite-blocked polyisocyanate Prepolymers not the same in all known textile finishing processes Success can be used.

From US-A-3,898,197 and GB-A-1,062,564 are bisulfite-blocked polyiso cyanate prepolymers known to modify keratin fibers can be used.

The through the equipment with the bisulfite-blocked polyisocyanate prepolymers achievable freedom from shrinkage and influencing the grip of the textile materials however, usually to a significantly reduced softness of the finished Materials. For this reason, the equipment usually becomes soft added makers who compensate for this disadvantage. An overview of the  various known types of plasticizers and their properties is in the Publication by P. Hardt, Melliand Textilberichte 91/990, p. 699 included.

Components K1 are present in the textile treatment agents according to the invention and K2 in a weight ratio of (0.1-5): 1 and preferably of (0.4-2.5): 1 in front.

Apart from the components K1 and K2 mentioned above, this can Textile treatment agents according to the invention still contain other ingredients, such as they are common with textile auxiliaries. These include protective colloids, perfumes, Fungicides or bactericides, foam suppressants and UV protection agents.

For easier handling, it has proven useful from the textile according to the invention to produce treating agents aqueous preparations. These watery preparations gen contain 10-90 wt .-%, preferably 30-70 wt .-% of the Tex according to the invention detergent.

The invention further relates to a method for equipping natural ones and synthetic textile materials, in which these textile materials with the inventions  text treatment agents according to the invention or their aqueous preparations be delt.

In particular, this process is carried out by treating the textile materials with the textile treatment agents or their aqueous preparations in the pull-out process ren (reel skids, nozzle-dyeing unit) or in immersion, spray or foulard drive. Also for these methods for applying the textile according to the invention treatment agent on the textiles is expressly referred to US-A-3,898,197, GB-A-1,062,564 and DE-PS-24 14 470.

The textile treatment agents according to the invention are preferred in an amount of 0.5-5% by weight, preferably 1-4% by weight in the exhaust process or with 5-50 g / l Liquor, preferably 10-40 g / l liquor used in the padding process, based on a 100% fleet pick-up. The fleet ratios can vary depending on the type of application vary between 1: 1 and 1:30.

The textile treatment according to the invention has proven to be particularly advantageous solvent in the exhaust process from a short liquor with nozzle dyeing systems on the To apply textiles.

The textile materials that can be used can be natural and / or synthetic Fiber materials exist. Cellu, for example, are natural fiber materials loose fibers such as cotton, viscose or rayon, as well as wool or silk net. As synthetic fibers such. B. polyamide, polyester or polyacrylonitrile can be used.

The textile treatment agents according to the invention improve the hydrophilicity of the be traded textile materials significantly, with the soft feel and high upper surface smoothness is retained.

Another advantage of the textile treatment agents according to the invention is their excellence wind-up behavior. While the known component K2 (bisulfite-  blocked polyisocyanate prepolymer) alone is very poor in the extraction process can be applied to textiles, the combination of components K1 and K2 in the textile treatment agent according to the invention the implementation of the pull-out process while maintaining a permanently equipped, hydrophilic textile material. This result is unexpected because a combination of component K2 with a State-of-the-art plasticizers (e.g. the one described in DE-OS-31 38 181 ) as well as component K2 alone when used in the pull-out procedure only leads to an insufficient fleet statement.

There is an additional advantage of the textile treatment agents according to the invention in that textile materials equipped with these textile treatment agents have been significantly reduced surface resistance and thus anti have electrostatic properties. What is particularly surprising here Persistence of these anti-electrostatic properties: The reduced surfaces resistance is still present after several washes of the textile material.

The textile treatment agents according to the invention also have an advantage sticky behavior when stored at low temperatures. For textile treatment means with the usual plasticizer compositions of the prior art e.g. B. contain paraffins and waxes, fall under the influence of low temperatures the active ingredients in solid form and can not even by heating again be emulsified. It is with the textile treatment agents according to the invention however, at any time easily possible to use again by heating Emulsions.
